8 Claims. (Cl. 68-205) .My invention relates to :a thread manufacturing or treating apparatus of the general typeset forth in my prior Patents Nos. 2,543,031 :of February'27, 1951, and 2,616,155 of November 4, 1952.

One object of the invention is to produce an improved apparatus of the type disclosed in'saidspatents.

In the type of apparatus referred to, various treating liquids are used in processing:the thread. In order to make sure that the variousliquids needed are present in suificient quantities, and because his difficult, if not impossible, to gauge the liquid requirements exactly, it is the practice to supplythe "various liquids in relatively excessive amount. But, :because at least some of the liquids used are expensive, because the presence of liquids in excessive quantities will-result in intermingling of the various liquids delivered to adjacent zones on the roll with obviously undesirable consequences, randbecause the presence of an excessive quantity of one reagent or another may, of itself, produce undesired results, it'i's desirable to remove :excess liquids so {88 regulate --,the

quantities of the various liquids =whichiare allowed-to remain on the filament ,ononzthe :rolls flufiingmovement of the filament through-successiveizonesalonasuchjrolls. It is also desirable that the excess liq ids be :remoyed, as far as possible, in a segregated rmannerssonas :to facilitate reclamation and =reconcentration of :the Wariolls liquids.

To this end, I have-heretofore deyised the liquidxscraping and segregating apparatus showniin myqpr'iorjPatent No. 2,634,449, in which the liquid astiraperszfitdnrgcd against the roll by 1 means of'rsprings, rnndfire satisfactory for most uses. However, =lihave'idiscovcrejdsthat1if the scraper is urged .againstthe .roll :by something :which is more sensitive, more wielding, :and -.more .readily iadjustable, better results can be; obtained.

It is therefore a :further, and insure (specific, .object of the invention to produce lan improyedrliquid scraping .and segregating means of the type disclosed'zin :saidnPatent No. 2,634,449.

According to my-invention,rl-.use a:;pneumatic.=pressure member for urging'the scrapcrzagainstvtheroll and Lmount the pneumatic-pressure applying member in suchza manner'as to enable 'it to :applyconstantfiollowing pressure over the entire surfaceof-thescraper.

The full nature .of the'qinvention will be runderstood from the following :specification .z-and :the accompanying drawings, in which:

The apparatus shown in Fig. 1 includes. anumber of rolls 10, 11, 12, 13, 14, 15, Y16 and 17 the ;opp osite ends of which are journalled in end plates '18 and 20 which are mounted on a center post 22. Ihe center post 22 is carried by a suitable frame not shown. The apparatus further includes a motor M, which, by means of gears, not shown, rotates rolls it! to 17 on their-respective, individual axes. The end .plate 18 is secured by a not or the like 24 and upon loosening of .the nut, the ,end plate 18, and the ends of the rolls journalledtherein, may be rotated ,slightlyrelative to .end plate-20 to skew theaxes of the rolls 10 to ,17 and thusform-athread storing and advancing device. The structure and operation of the thread storingand advancing reelform .no part of the present invention, and they are-therefore -not shown nor described. For .a morecomplete understanding of the structure and operation of ihe .threadstoring and advancing device, reference may he had tomy above mentioned and .other patents. ,For the ,purposeiof invention it is enough to state that, when the thread 26 is wound about the receiving endof t-hereel-soasio encompass all of the rolls, it will fornra helixthe convolutions of which will move, .longitudinallyof the reel,,from the receiving to the, discharge. end of the reel. .In Fig. ,1 the thread 26 is shown as a nascent filament .which has just been formed by extruding viscose through a spi nnerette 28 into a coagulating bath 3!}. Ihis,, is.hyl,way of illustration only as the source of the threadis immaterial. As the thread movespver suecessiveportionsor zones of the roll 11 (or rolliii), various treating liquids are poured over the thread fronrspaced nozzles N. ,These liquids are conventional and have been incommon use in the industry for about fifty years and therefore need notbe described, chemically or functionally, beyondsaying that suiphuric acid will be applied in one ,zone,. so dium hydroxide in another zone, water-in another zone,,sgap in another zone, sodium carbonate' in another zoneetc. Asthe thread traverses the portion of the roll to theleft of the endmost nozzle, as shown in Fig. ljthe filanient is dried by means of a heater, which forms no parnof the present invention and which may beof t e typels hoyvn in my prior PatentNo. 2,613,451. '7

In order to remove-excess iiquidsfrom rolls 10 andll (and from other rolls,'if desired) Iprovide the slcraper .shown in "Fig. 10 and I mount the pressureapplying member as shownin Fig. .3 or -in 'Fig. 7. .In either case, the scraper is urged against the roll byrneans of the pneumatic pressure applying member ofaFig. 1.6. ivVhen a fine thread is to be produced forusedn textile fabrics, .iW Scrapers A a a e-u sid r yt id n-a fi hq .;in Fig. 1. Thisis due ;to :the fact that;this,.;type.:of hrea req ir be r and ng,er-.-regeneration and di isjhing. On the other hand when a coarse thread such as tire cord is to be made, the regeneration treatment is shorter and only one wiper A is used at the receiving 'end of 'the reel. In either case, the scraper includes an arcuate shell 31 the concave face of which is provided with wiping or scraping elements 32' which form .a series of connected upright and inverted V formations,

as best shown in Fig. 10. At the apex of each upright V formation is a drain hole 33, and below each shell is a trough 34 which is preferably provided with partitions 36 'to form separate compartments for receiving the ditferent liquids drained through holes 33. The open, or upper ends, of the V formations, in single units or in multiples, are coextensive with the zones on the roll .to' which the different liquids are delivered. For example,

the space between points C and D will correspond to between points D and E will correspond to the zone to which soap is delivered and so on. Obviously, if a treating zone is particularly long, it may correspond to the distance between points C and E instead of to the the" zone to which acid is delivered, and the space space between points C and D only and so on. It will be noted that the inclined scraping elements 32, being continuous, scrape over the entire surface of a roll to which they are applied. Also, the scrapers which terminate at C and D, for example, will direct the liquid scraped thereby from the corresponding zone on the roll 11 to the endmost drain hole at the left end of Fig. 10 and so on.

' In order to apply following pressure against the scraper and in order that such pressure be constant and uniform throughout I have devised the pneumatic pressure applying member 38 which is best shown in Fig. 6. The member 38 is preferably a rubber tube which is coextensive with shell 31 so as to have yielding contact with the entire convex surface of the shell. The memher 38 may be filled with air under the desired pressure and sealed, or it may be connected, by pipe 40 to a source of compressed air, not shown. If desired, a valve 42 which operates to maintain the pressure at a constant value, or which can automatically regulate thepres- A and B are used, one member 38 can be used which is coextensive with both of the shells or a separate pressure applying member 38 can be used for each separate scraper. The member 38 is carried in a housing 46 and its diameter is such that, when it is deflated as in Figs. 5 and 9, it will not project beyond the inner edges48. of the housing, and that, when it is inflated,

it will bear against the convex side of shell, or shells,

31 to press the scrapers 32 against the roll 10 or -11.

See Figs, 4 and. 5 and Figs. 8 and 9..

Since air pressure within member 38 is equal in all directions it follows that it will exert more uniform pressure against the scrapers than is exerted by a spring such as that shown in my said prior Patent No. 2,634,449.

It is of course possible to use a cushion member which is solid or hollow and the resiliency of which is depended on to exert the desired pressure without the 'use of compressed air. For example, a rubber tube, or

sure within member 38 may be used. When two scrapers by the bearing of shaft 52 of the roll. If this support is not enough, the other end of the housing can also be supported by a plate, or bracket, not shown, which can be carried by end plate 22, by center post 18 or by any other fixed frame. 'The exact arrangement does not matter as the point is that, in this embodiment, the housing 46 which'carries pressure member'38 is not the shells 31 may be removed.

4 carried by the shaft of the roll to which the scraper is applied but by an independent support.

In the structure of Figs. 7 to 10, the housing 46 is carried by brackets 54 which are carried by the opposite ends of the shaft 52 of the corresponding roll so that each roll and its scraper assembly form a unitary structure. In this arrangement, the scraper, being carried by the roll, it will adapt itself more readily and more accurately to movement or change of position of the roll than it can when the housing 46 is carried by a support which is independent .of the roll as in Fig. 3.

In all cases, each of the shells 31 is provided with one or more lugs 56, which, when the reel is assembled, rest upon the upper walls of housings 46.as clearly shown in the drawings. The engagement of lugs 56 with the tops of the housings 46 serves to prevent rotation of the shells 31 and they also serve as handles with which It will also benoted thatthe shells31 are not fastened tov anything in any way so that'they are free to'pivot in all directions so stantly, readily and accurately adjust their contact with the rolls, and that the scrapers are urged against the rolls with a yielding pressure which is uniform throughout and which can adjust itself in a localized manner. In other words, if there is moreresistance at one point and less resistance at another point,-the corresponding portions of the resilient member 38 will yield or will follow as the case may be.

In Fig. 11 I show a modification in which the shells 31 are placed back'to back with their concave'faces abutting adjacent rolls and I use a single pneumatic pressure applying member 56 located between and adapted to bear against the convex sides of the shells 31. The

single pneumatic pressure applying member may be n1ount'ed in any'suitable manner. As shown in Fig. 11, I provide a" housing 58 provided with side openings through which the pressure member bulges so as to press against the shells 31.

It will be noted that, when the tube 38 is collapsed, as

in Figs. 5 and 9, there is ample play between the wiper and the roll and between the wiper shell and the housing 46 whereby the entire wiper assembly can be lifted out, or inserted in position, easily and without removing any of the parts. In other words, the wiper assembly is attached'to nothing and is supported in position only by lugs 56 resting on the top wall of housing 46 and the only engagement of the wiper with the roll is that caused by the pressure exerted by pipe 38 when it is inflated.

What I claim is:

1. A thread manufacturing apparatus including at least one rotary roll over which the thread is adapted to pass, means for applying at least one liquid to roll, a wiper engaging a portion of said roll for scraping off liquid from a portion of said roll, and an air cushion mounted in pressure contact with said wiper and serving yield- .ably to urge said wiper against said roll, said cushion being formed of resilient elastic material.

2. The structure recited in claim 1 in which said wiper is elongated and said air cushion is in the form of an elongated cylindrical member extending longitudinally of the wiper.

3. A thread manufacturing apparatus including a supporting frame, at least one rotary roll over which the thread is adapted to pass, a shaft for said roll carried by said frame, means for applying at least one liquid to said roll, and means for scraping off liquid from a portion of said roll, said means including an elongated wiper having a concave inner face adapted to contact the roll, an elongated support adjacent the outer side of said wiper, an elongated, resilient, elastic, hollow member carried by said support, means for admitting compressed air into, and retaining it in, said hollow member, to expand said hollow member into contact with the outer side of said wiper to press the latter with following yield ing pressure against said roll.

4. The structure recited in claim 3 in which said support is carried by the ends of the shaft of the roll.

5. The structure recited in claim 3 in which said support is carried by said frame.

6. The structure recited in claim 3 in which said wiper is loosely placed between said roll and said support and a lug extending laterally from the outer side of said wiper and resting on said support, said lug being the sole means for limiting the downward movement of said wiper and for preventing rotation thereof with the rotation of the roll.

7. The structure recited in claim 3 in which said support is generally U-shaped in transverse section with the open side of the U facing the outer side of the Wiper and in which the diameter of the hollow member, when deflated, is smaller than the length of the limbs of the U whereby, in the absence of predetermined air pressure therein said hollow member will not contact the wiper.

8. The combination with a thread manufacturing apparatus of the type which includes a number of rolls arranged to form a thread storing and advancing reel, means for applying a liquid to the thread as it passes over at least one of said rolls, and an elongated scraper engaging an elongated portion of the surface of said one roll for removing some of said liquid from said roll, of means for applying following pressure to said scraper to urge it against said roll, said means including an elongated, resilient, elastic hollow member, means for supplying fluid pressure to the interior of said member, and means for mounting said hollow member adjacent said wiper in such a manner that, when said hollow member is inflated it will bear against the corresponding portion of said scraper and so that, when said hollow member is deflated, it will be out of contact with said scraper.
